摘要
FIELD: chemistry.;SUBSTANCE: method includes sandblast processing for roughening, etching in acids to remove admixtures and obtain pure titanium on the surface, burning-degassing to remove dissolved gases and reduce tension, single-phase or two-phase anodising (electrochemical oxidising) and burning in furnace to structure crystals and remove bound water from the surface pores. Burning-degassing is carried out in vacuum at temperature 300-770°C, anodising is performed by constant or pulse current (0.5 Hz) in electrolyte solution with forming voltage 25-130 V, burning in furnace is performed at temperature 300-550°C.;EFFECT: method makes it possible to obtain porous nanostructured 1-10 mcm thick oxide film, which consists of open nanotubes of titanium oxides with pore size 40-140 nm of hexagonal or tetragonal order.;6 cl, 3 dwg
